Abstract : Additive powders of Al, Mg, B, Zn, Ti, and W in test mixtures of NH4ClO4 with bitumen and polymethylene-methacrylate, and of KClO4 with bitumen, showed that adding finely divided metals to compounds having a weak dependence of combustion rate on pressure strengthens this dependence, whereas if the dependence u(p) is strong for the original compound, additives weaken this dependence. Experimental results agree well with the theoretical model, which allows for simultaneous occurrence of homogeneous reaction between products of gasification of oxidant and or organic fuel, and the heterogeneous reaction of combustion of metal particles.
